What is the 417 Hz frequency?
417 Hz is one of the traditional Solfeggio tones, a set of pitches from devotional and chant music. There is no audio study of 417 Hz. Calm music and sound have been studied for stress in general (Thoma et al., 2013); that work was not a trial of 417 Hz. Freqium offers it as a calm listening tone.
Proposed mechanism
A steady mid-range tone. Like other calm sounds, it can make it easier to slow down; no effect specific to 417 Hz has been shown
Traditional uses
These are the uses traditionally associated with 417 Hz. They come from cultural practice, not from clinical trials, so read them as intentions for a session, not as outcomes.
Who is this for?
People often choose 417 Hz for:
Experience it yourself
Reading about a frequency is one thing. Feeling it is another.
The science behind 417 Hz
Brainwave entrainment is the idea that the brain’s electrical activity can fall into step with a steady rhythm you hear. A related response, the Frequency Following Response (FFR), can be measured with EEG.
For 417 Hz the reasons are mostly traditional. The papers below are background on sound and the brain, not trials of this frequency.

How to use Solfeggio 417
Suggested session
20-30 minutes, whenever you want a calm listen. Individual experiences may vary
🎧
Use headphones
Over-ear or in-ear, at a low volume. They keep the tone clear without turning it up.

Find a quiet space
A calm room makes it easier to settle in and notice how you feel.

When Science Listens to Sound
Dr. Tamara Goldsby
Researcher, Department of Family Medicine · University of California San Diego
Study summaryAn observational study of a single singing-bowl meditation session, without a control group.
In 2017, Tamara Goldsby and colleagues at UC San Diego asked 62 adults to rate how they felt before and after a one-hour sound meditation with singing bowls, gongs and bells.
After the session, participants reported feeling less tense and more at ease on standard mood questionnaires.
The study had no control group, so it cannot say how much of the change came from the sound itself rather than resting quietly for an hour.
We share it as an honest picture of where sound-meditation research is: promising, early, and worth trying for yourself.
